Magnetic Separation: This is based on differences in magnetic properties of the ore components. If either the ore or the gangue (one of these two) is capable of being attracted by a magnetic field, then such separations are carried out (, in case of iron ores). The ground ore is carried on a conveyer belt which passes over a magnetic roller.
